Abstract: ABSTRACT OF THE DISCLOSURE       A method is disclosed for relining buried pipeline with interconnectable plastic type pipe sections.  The method comprises gaining acess to an open end of the buried pipeline, such as through a manhole, passing pipe sections down the manhole and inserting individually each pipe section into the buried pipeline open end.  Each pipe section is of a length to permit, within the confines of the manhole, insertion of each pipe section into the pipeline open end.          Each pipe is of a diameter to fit within the pipeline.  The pipe section to be inserted is interconnected to the pipe section already inserted within the buried pipeline.  Such interconnected sections are sequentially moved into the buried pipeline to permit insertion of the next pipe section into buried pipeline until the entire length of the pipeline to the next access area has been relined.

Abstract: ABSTRACT      The ear plug (40) includes an elongate body with a rounded tip portion and of an elastic material enveloped by a deep-drawn sheath (41) of thin flexible plastics film material. Rearwardly the plug preferably has a neck portion from which the sheath projects in the form of a stiffer collar or flange. Production of the car plug in-cludes deep-drawing a thermoplastic film or foil into a sheath with desired thickness distribution, and filling the sheath with elastic material (53). Filling may take place simultaneously with deep-drawing, the body of elastic material constituting a die for deep-drawing in a forming hole (45), or after the deep-drawing. In the latter case, an elastic die body is used  to advantage, the shape of which generally corresponds to that of the finished plug, for deep-drawing in a forming hole suited to the die body.

Abstract: ABSTRACT OF TIE DISCLOSURE A method for measurement of distance using the curl-free vector potential rad-iation field.  The system includes current-carrying apparatus for generating a predominantly curl-free vector potential field and apparatus for modulating the current applied to the generating apparatus.  The receiving apparatus includes a detecting apparatus with observable properties that vary with the application of an applied curl-free vector potential field, a demodulation apparatus for determining the magnitude of the curl-free vector potential field.  The magni-tude of the detected curl-free magnetic vector potential field can determine the distance from apparatus generating predetermined periodic changes in the curl-free vector potential field.  The vector potential field can be established in conducting and  opaque materials which are not capable of transmitting typical electromagnetic radiation.
